10 Compact Modules CKK Structural design of motor mount and coupling A motor can be attached to all Compact Modules with ball screw drive by means of a motor mount and coupling. The motor mount serves to fasten the motor to the Compact Module and acts as a closed housing for the coupling. The motor s drive torque is transmitted stress-free through the coupling to the Compact Module s drive shaft. Our standard couplings compensate the system s thermal expansion. 1 Motor 2 Flange 3 Coupling 4 Compact Module 1 2 3 4 Bosch Rexroth AG, R999000499 (2018-04)
CKK Compact Modules 11 Structural design of timing belt side drive All Compact Modules with ball screw drive offer the option of attaching the motor via a timing belt side drive. This makes the overall length shorter than when attaching the motor with a flange and coupling. The compact, closed housing serves as protection for the belt and as a motor bracket. Besides this, various gear ratios are also available (depending on size): i = 1 i = 1.5 i = 2 The timing belt side drive can be installed in four directions: below, above (RV01 and RV02) left, right (RV03 and RV04) 1 Deflection housing made of anodized aluminum 2 Compact Module 3 Counter bearing at the screw journal in size CKK-070 4 Toothed belt 5 Motor 6 Pre-tensioning the toothed belt: Apply pretensioning force F pr to motor (F pr is provided upon delivery) 7 Cover 8 Fastening of belt pulleys with tensioning units 9 Cover plate 1 3 2 4 5 6 7 8 9 F pr R999000499 (2018-04), Bosch Rexroth AG
